Application filed May 7, 1914. Serial No. 837,055.

To all 'whom t may concern Be it known that I, JOHN D. CURTIS, a citizen of the United States, residing at Worcester, in the co-unty of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Manure-Spreaders, of which the following, taken in connection with the accompanying drawings, is a specification.

.The present invention relates to that class" of manure spreaders in which a mo-vable bottom is utilized to carry the load toward a beater or other disintegrating device, adapted to distribute the manure over the ground traversed by the spreader. In machines of this type it is desirable to suspend the movable bottom as close to the ground as possible in order to facilitate loading of the manure into the body of the spreader.

An object of the present invention isto provide a construction in which the sills of the body of the spreader, upon which it 1s customary to support the movable bottom, are supported low enough to provide for convenient loading.

A further object is to provide for a convenient supporting of said sills upon the rear axle of the spreader, which is journaled below said-sills, but above the main load supporting section of the movable bottom.

Other and further objects will appear from the following description taken in connection with the accompanying drawings, in which- Figure l is a longitudinal vertical sectional view of a manure spreader embo-dying my invention. Fig. 2 is a section on line ca, Fig. i.

Similar reference characters refer to similar parts in the diiierent figures.

The numerals 1, 1, denote the sills upon which the body of the spreaders is supported. Between the sills 1, 1. are cross bars 2, which support the longitudinal angle bars 3, 3, between which the ro-lls 4, 4, are journaled. Upon the rolls 4 is supported the movable bottom, which in the present instance is endless and consists oftransversely of the arrow a, Fig. 1. The beater 8 is journaled at the rear end ofthe spreader, above the sprocket wheel 7, and a rapid rotation is imparted to the beater by a mechanism, not shown, which carries the heater teeth 9 in a circular path, inthe direction of the arrow o. At the front end of the spreader the sills l are bent upwardly, as shown at 10, Fig. 1, withtheir forward ends connected by a cross bar 11 of the same width as the body of the spreader. An angular framework 12 is mounted upon the upturned portion of the sills having its vertical member 13 supporting the headboard 14. Mounted upon the cross bar l1 is the drivers seat 15. Each sill 1 is bent upwardly from a point in front of the rear axle of the spreader, and then downwardly, the rear extremities of said sills being disposed beneath the beater 8. An upwardly inclined section 16 and a downwardly inclined section 17 ofeach sill are thereby formed, and at the meeting points of said sections suitably shaped straps 18 are hung, from the under surfaces of said sills for the support of sleeves 19, in which the ends of the rear axle 20 are journaled. Upon the ends of said rear axle the rear wheels of the spreader are journaled, one of which is shown at 21, Fig. l, having a pawl and ratchet connection with said axle, as is usual in manure spreaders, causing the rotation of the wheels 21 to rotate said axle, which is utilized as the driving means for the beater 8 and the rear sprocket wheel 7, by connecting mechanism common to manure spreaders, but not herein shown or deinvention. The longitudinal angle bars 3 which form the track for the movable bottom follow the bends in the sills 1, causing said movable bottom to assume the upward inclination as indicated at 22, in front of the rear axle, to carry it over said axle, and a downward inclination, as indicated at 23, at the rear of said axle.

By the above described construction, the main load supporting section of the movable bottom is maintained low enough to permit of convenient loading of manure to the spreader, the portion of the sills supporting the same being disposed below the plane of the rear, axle. Nevertheless, by reason of the shape of said sills, the body of the spreader is supported upon the rear axle, rather than suspended from it, thereby securolined sections 16 and 17 of the movable bot.

tom. By the employment of the longitudinal bars 3, 3, however, the rows of supporting rolls 4 may be brought closer together obviating the necessity of a central row of rolls.

I claim, 1. In a manure spreader, a rear axle, av

pair of sills supported above said axle, a track for a movable bottom supported throughout its length upon said'sills, said sills being bent upwardly and downwardlyV to carry said track over said rear'axle, and

. a movable bottom supported on said track.

2. In a manure spreader, a rear aXle, a

pair of longitudinal sills having portions thereof overlying said rear aXle and disposed throughout the major portion of their lengths below the axis of said axle, and a bottom supported by said sills and movable in a path defined by the upper surfaces thereof. l
